Case Type   : dbcompatibility-whale
Case Name   : 函数gms_pipe.next_item_type()清空指定的管道
Create At   : 2023/12/12
Owner       : @zou_jialiang050
Description :
    1.在本地缓冲区中设置指定的消息，select gms_pipe.pack_message('testcase');
    2.存储在本地缓冲区中的数据发送到指定管道，select gms_pipe.send_message('PipeTest');
    3.清空管指定的管道，select gms_pipe.purge('PipeTest');
    4.接收指定管道中的信息，接收超时，select gms_pipe.receive_message('PipeTest',2);
    5.函数select gms_pipe.purge();少参
Expect      :
    1.成功
    2.成功
    3.成功
    4.成功
    5.失败，合理报错
